I cant figure out what is wrong the truck lags bad in 1st gear then when its shifts to 2nd or about 3-4 seconds after i kick on it the power is awesome any suggestions on what tables i need to fix to make the truck where i can take off quickly?

A buddy of mine has an LB7 that has the same problem. We think it's a weak CP3

We figured my problem out it was my fault I wasn't putting my stock tune in imperial units before running a script.
